=head1 NAME
Catmandu::Fix::Builder - Base role for Catmandu fixes
=head1 DESCRIPTION
This role expects a C<_build_fixer> method that produces a coderef that
transforms the data. Used in combination with L<Catmandu::Path>
implementations, data manipulations can be described in a relatively high-level
way. Most fixes shipped with Catmandu work this way and can be used as a
starting point to write your own fixes.
=head1 SYNOPSIS
package Catmandu::Fix::my_fix;
use Catmandu::Sane;
use Moo;
with 'Catmandu::Fix::Builder';
sub _build_fixer {
sub {
my ($data) = @_;
$data->{foo} = 'bar';
$data;
}
}
